Nova Compo 0 is a self-adhesive, two way color-changing, light-curing orthodontic composite with high bond strength for faster bracket bonding. The composite is self-adhesive and can be applied without bond. However, Nova Ortho Bond is recommended for excellent bond strength. Thanks to its color change feature, the color turns green when the temperature is reduced by applying water or air to the tooth when the bracket is removed. This makes it easy to distinguish the tooth for cleaning. When the temperature returns to normal, the color becomes transparent. Indications: - Bonding ceramic and metal brackets.
